Some of their bodies were discovered more than 50-years-ago, but their identities still remain a mystery. A total of 12 people have still not been named, years after they were found dead in Greater Manchester.
The deaths - which date all the way back to the beginning of 1970 - remain unsolved despite investigations launched by Greater Manchester Police. Loved ones were tragically never traced for these cases, so the bodies now lie in unmarked graves.
Two out of the cases 12 on Greater Manchester's list may hide a sinister story. One is the partially-mummified body of a woman found hidden in a cellar in Bolton in 1982, the other a woman found by workmen at Angel Meadow, in Manchester city centre, in 2010, who had been sexually assaulted and murdered.
